Re: interesting math riddle

ill explain in white.
<font color="white"> we know there are 18 heads. we take 18 coins randomly and put them into a pile. we flip the coins. now lets say that we took 10 heads, leaving 8 in the other pile. once they are flipped the 10 heads become tails and the 8 tails become heads.
lets do it again. this time we get 1 heads in our 18 pile, leaving 17 heads in the other pile. flip the 18 and now we have 17 heads.
as long as u take the same amount of coins as tehre are heads and flip them it will always work. </font>
